IPC: H04L12/70
Filed: 1995-12-11
Abstract: PROBLEM TO BE SOLVED: To obtain the information communication equipment and the information communication method in which data received by each equipment is maintained as the same contents by allowing a receiver side equipment to rearrange definitely and process the data transmission sequence from each equipment interconnected by a network. SOLUTION: An event to update data by the user entry is sent once by a transmission section 16 to its own equipment and other information communication equipments as a data packet, an information communication equipment 1 uses a reception section 17 to receive the data and data in a main storage section 23 via a control section 18 are updated and indicated for the user by a user output of an output section 20. Since the event by the user entry does not directly update the data in the main storage section 23, events of all the equipments including the event by its own equipment are processed simply and effectively in a definite order. Thus, the information communication equipment and the information communication method to keep the data received by each equipment as the same contents are obtained.
